* At first he may seem rude and ignorant but he’s actually a sweetheart despite his awful friends. He doesn’t consider them as friends, more-so acquaintances. He doesn’t take people’s crap and just blows people off when they do something he doesn’t like. He’s a loyal person and doesn’t judge others that often. 

* Louis is half vietnamese, his voice is up to what you think he sounds like.
